GUIDING DEVICE FOR SUSPENDED SEPARA'IOR-DRUMS.

, Specification of Letters Patent.

Patented Feb. 25, 1908.

Application filed September 4. 1906. Serial No. 333.095-

To all whom it may concern:

Be it known that I, IVAR PETER BAGGER KNUDSEN, director, sub'ect of Denmark, residing at 56 Svanemollevej, Copenhagen, have invented new and useful Im rovements in Guiding Devices for SuspendetFSeparator- Drums, of which the following is a specification. I

Separator-drums, of the kind which are suspended on a shaft in such a manner that they are actuated thereby but at the same time may'move freely relatively tothe shaft, present the great drawback that the separator-drum swings too violently, thereby making the motion very inconstant.

The object of the present invention is to remedy this objection by employing with the guiding device, a device which without influencing the connection between the drum and the shaft, guides the drum'in such a manner that it moves without jerk or wabble.

The accompanying drawing shows an embodiment of the invention in vertical section.

Referring tothe drawing, a is the separator-drum, b the driving shaft on the upper end 0 of which the separator-drum is suspended in such a manner that it is capable of moving freely with relation to the shaft.

(1 is a guide or guide-coupling fastened to the bottom of the separator. This guide (I is"fitted on and is capable of turning freely on the upper end of the hollow guide-pivot e. The latter is provided with a ball-guide f inserted in a fixed bearing 9. The lower part of the ball-guidef is supported by an elastic andsplit cylinder h which also maybe made of springs and which presses-or bears against a ring 11 made of metal, leather or ebonite or the like and fixed on the lower part of the guide-pivot, said ring receiving all the forces transmitted from the separator-drum to the ball-guide and guide-pivot without producing 'a reactionary effect. is is a pressure-nut fastened in the fixed bearing. This nut serves'for keeping together the parts and' forms the bottom friction-surface for the nng 'e.

From the foregoing description it will be seen that the drum is guided on a guidepivot which in turn is supported by a part capable of receiving the movements trans- 'mitted from the drum without producing reactionary effects. In other words, there is provided a friction means retarding the vibrations of the guide-pivot to prevent undue vibrations of the drum. relatively to the shaft.

Having thus described my invention, What I claim and desire to secure by Letters Patcut is:

1. In a centrifugal separator having a separator drum carried by a vertical shaft imparting rotation to the drum, the combination of a guide pivot for the drum, said guide-pivot being only acted upon by horizontal stresses, a fixed bearing having a ball-guide for said 7 ivot, and retarding nonreacting means inc osing the guide-pivot in spaced relation to the ball-guide, substantially as and for the purpose set forth.

2. In a centrifugal separator having a separator drum carried by a vertical shaft imparting rotation to the drum, the combination of a guide pivot for the drum, said pivot being only acted upon by horizontal stresses, a fixed bearing having a ball-guide for said pivot, a ring surrounding the guide pivot in spaced relation to the ball-guide,-

and a pair of members having surfaces be tween which the ring is clamped in such a manner that it can movein a direction transvers'ely to the axis of theguide pivot by overcoming the frictional resistance, substantially as and for the pur ose set forth.

In testimony whereof I ave signed my name to this specification in the presence of two subscribing witnesses.
